PROBLEM TO BE SOLVED: To enable an environment correspondence type vehicle to use only clean energy, and to enable the user of car sharing to recognize that only the clean energy is used.

SOLUTION: When a power generation base point supplies renewable energy to a car station 20, an energy management server 100 receives the place of the car station to which the renewable energy has been supplied from the power generation base point, and transmits power generation method data relating to the power generation method of the power generation base point to the car station to which the renewable energy has been supplied. Then, the car station 20 receives the power generation method data from the energy management server 100, and when receiving energy supply from the power generation base point, selects one supply destination to which the renewable energy is supplied on the basis of the received power generation method data, and conducts charging to the selected supply destination.

PROBLEM TO BE SOLVED: To provide a clean energy generation device that has an extremely high energy balance ratio, has a compact size and light weight and can be produced at low cost, and can supply clean energy continuously for a long period.

SOLUTION: A CO2 refrigerant is charged as a working fluid in a closed power cycle 15 under predetermined pressure equal to or lower than a supercritical point, and the low-temperature low-pressure CO2 working fluid is raised in pressure by a compressor 27 with a pressure equal to or higher than the supercritical point so as to generate a supercritical fluid. An electric power gas generator 42 is heated up to a temperature equal to or higher than the supercritical point with pulse electric power generated by supplying stored electric power of a power storage unit 20 to a pulse power source 28, a supercritical power gas generated by bringing the supercritical fluid into contact with the electric power gas generator is expanded by a movable piston 200 up to a predetermined pressure so as to generate mechanical energy as first clean energy, and a part of the mechanical energy is supplied to an electric power generator 25 so as to generate electric power as second clean energy.
